Porsche 911 S

The Porsche 911 (pronounced Nine Eleven or German: Neunelfer) is a two-door, 2+2 high performance classic German sports car made since 1963 by Porsche AG of Stuttgart, Germany. It has a rear-mounted six cylinder boxer engine and all round independent suspension. It has undergone continuous development, though the basic concept has remained little changed. The engines were air-cooled until the introduction of the Type 996 in 1998, with Porsche‘s „993“ series, produced in model years 1994–1998, being the last of the air-cooled Porsches.

The 911 has been modified by private teams and by the factory itself for racing, rallying, and other forms of automotive competition. It is among the most successful competition cars. In the mid-1970s, naturally aspirated 911 Carrera RSRs won major world championship sports car races, such as Targa Florio and 24 Hours of Daytona, even against prototypes. The 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979 and Porsche won World Championship for Makes titles in 1976, 1977, 1978 and 1979 with 911-derived models.

In the 1999 international poll to determine the Car of the Century, the 911 came fifth. It is one of two in the top five that had remained continuously in production (the original Beetle remained in production until 2003), and was until 1998 a successful surviving application of the air- (now water-) cooled opposed rear-engine layout pioneered by its ancestor, the Porsche 356. It is one of the oldest sports coupé nameplates still in production with one million manufactured as of May 2017.
The first editions of the 911 had a rear-mounted 130 PS (96 kW; 130 hp) Type 901/01 flat-6 engine, in the „boxer“ configuration like the 356, air-cooled displacing 1991 cc compared with the 356‘s four-cylinder, 1582 cc unit. The car had four seats although the rear seats were small, thus it is usually called a 2+2 rather than a four-seater (the 356 was also a 2+2). Available was a four- or five-speed manual „Type 901“ transmission. The styling was largely by Ferdinand „Butzi“ Porsche, son of Ferdinand „Ferry“ Porsche. Erwin Komenda, the leader of the Porsche car body construction department who initially objected, but later was also involved in the design.

In 1966, Porsche introduced the more powerful 911S with Type 901/02 engine producing 160 PS (120 kW; 160 hp). Forged aluminum alloy wheels from Fuchs, with a 5-spoke design, were offered for the first time. In motor sport at the same time, the engine was developed into Type 901/20 installed in the mid-engined Porsche 904 and Porsche 906 with 210 PS (150 kW; 210 hp), as well as fuel injected Type 901/21 installed in 906 and 910 with 220 PS (160 kW; 220 hp).
